Title: Television receiver
Inventor: ISHIGURO MEGUMI
IPC: H04N5/44
Filed: 1987-03-23
Abstract: PURPOSE:To prevent malfunction by using an output of a count circuit so as to prevent malfunction of channel selection at antenna input selection and using an output of the counter circuit so as to control the display of the screen at the selection of external video input thereby making the threshold value of the counter circuit different depending on the selection of antenna input an external video input. CONSTITUTION:A horizontal synchronizing signal detected by a synchronizing signal detection circuit 16 is fed to a microcomputer 10, where the horizontal synchronizing signal per a prescribed time is counted. When the video signal of the number within a prescribed range is detected, it is discriminated that a video signal is inputted, and when not detected, it is discriminated that no video signal is inputted. Based on the result of discrimination, the AFT control is applied at channel selection to discriminate the invasion of an audio signal or noise and to control the display of the screen. The criterion differs from the channel selection and the screen display. Thus, malfunction at channel selection is surely prevented.

IPC: G10L25/90
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To extract the pitch of voice waveform with a small quantity of operation by restricting an interval to be a prospect in waveform at the time of computing a square error, so as to become an interval starting from the value approximate to the head value of waveform data to be examined. SOLUTION: A prospective value computing part 11 obtains the head value αof waveform data to extract a pitch out of digital voice waveform data stored in a data buffer 2, and computes the prospective value α± for pitch extraction on the basis of the head value α. A pitch prospect extracting part 12 searches out each position of the waveform data with the same value as the prospective value α±5 from the buffer 2. The interval length from the head value α to each position becomes the interval length of each pitch prospect. A square error computing part 13 computes the square error of each pitch prospect and outputs the pitch prospect with the square error having the shortest inverval length, as an extracted pitch.

IPC: G03F7/095
Filed: 1987-03-24
Abstract: PURPOSE:To improve storage stability by incorporating pullulan with a <=pH 2.0 organic acid radical and diazonium salt. CONSTITUTION:A photosensitive resin which contains diazonium salt as a photobleaching agent is applied on a resist film lower layer to form an upper layer and then the upper and lower layers are both exposed to form a pattern. At this time, the organic acid radical or carboxylic acid radical of <=pH 2 is incorporated in pullulan which is a polymer. Namely, prebaking is performed after the resist coating and the photosensitive resin consisting of diazonium salt and/or an organic solvent and a polymer are applied by a spinner. The upper and lower layers are both exposed to light 5 through a mask pattern 4 after the photosensitive resin is applied, and while the resist at the exposed part is developed with a developer (alkali developer) of the used resist, the photosensitive resin 3 is also removed together to form a fine resist pattern 2A. Consequently, the resolution is improved and the stability of the diazonium salt is improved.

Title: Optical disk alternation processing method
Inventor: MUTO AKIRA
IPC: G11B20/10
Filed: 1987-03-24
Abstract: PURPOSE:To easily and accurately detect data of alternation sectors by recording in the specific part of the alternation area the physical positions of a group having the failure sectors of more than a specific number and an alternation group. CONSTITUTION:When the failure sectors are more than two, a recording and reproducing optical system 5 is accessed to a leading part in which the alternation address table of an alternation recording area is recorded. When access is completed, the groups are decided and the whole failure group is re-recorded. When all data are recorded without failure, the optical system 5 is accessed to the leading part of the area and the alternation address table is re-recorded. If there are more than two failure sectors in the group at the time of reproduction and recording, the part in which the alternation address table of the alternation recording area is recorded is reproduced, and the alternated group is accessed, whereby a reproducing action is continuously executed. Since the positions of the alternation sectors are previously decided according to the above method, data of the alternation sectors can easily and accurately be detected.

IPC: F04D13/12
Filed: 1981-05-11
Abstract: PURPOSE:To enable the increasing of the amount of water by providing a reproduction pump at the upstream of a centrifugal pump while conducting each suction port through a bypath then making the slope of the water-lift curve sharp under low amount of water while making gentle under high amount of water. CONSTITUTION:Under low water flow where the impeller 8 will be in the operating range of a reproduction pump, the water will flow into a centrifugal impeller 11 to produce the high pressure water where a check valve 17 will close the outlet of a bypath 16. Consequently the water lift characteristic will have the sharp inclination as shown in the range A of the drawing. When the flow will exceed over the limit flow of the reproduction pump, the water can not be supplied to the centrifugal impeller 11 thereby the pressure at the sucking section of said impeller 11 will be made lower than that at the sucking section of the reproduction pump to open the check valve 17 and the water will flow directly into the centrifugal impeller 11 to continue the pump function thus to reduce the inclination of the flow-lift characteristic resulting in the high flow.
